I am on Long Island so our weather likely very similar. I've not used the LEDs long enough to have real world experience with the freezing issue.. just trying to do some forward thinking when I had them in and was able to feel the temp difference between the LED and H4s.@MikeM @WestCoastDan
The JK I bought (from a longtime friend) has had LEDs on it for over five years and there's never been an issue with frozen headlights. Now entering my second winter with it, and no freeze has resulted in less than stellar lighting.
Guess it depends on where you're at but here in the Northeast, New Jersey to be precise, I gets pretty damn effing cold and things freeze during the winter.
I moved away from the LEDs because I wasn't happy with the pattern of either set. I did like the hyper white color, but I'll play with a few different H4 bulbs when I have time.
